Websustain LTP into its late form. Overall, LTP can manifest in both early and late forms. Early-LTP can exist independent of protein synthesis but will decay over time. On the other hand, late-LTP is protein synthesis-dependent and is long-lasting. Thus, early-LTP and late-LTP serve as the cel-lular correlates of short-term memory and long-term WebTaken together, my findings show early-LTP of the CST EPSP in the dorsal horn and intermediate zone of the spinal cord that leads to early-LTP of the CST oligosynaptic response in the motor pools and wrist muscle.
